We design, build, and ship software that lasts.
Modern product engineering for mobile, web, and backend. Leadership that unblocks teams and commits code daily. Lean, testable architecture. Fewer moving parts. Code that documents itself and scales sensibly.
- Hands-on senior engineering—pragmatic leadership and daily code delivery.
- AI as co‑developer — acceleration without losing craftsmanship.
- Architecture you can keep in your head and evolve safely.
- Automation and CI/CD that keep momentum steady.
About
Who we are
Concise Consulting is a boutique product-engineering practice led by Ethan Nagel. We partner with venture-backed start-ups and internal product groups to untangle complexity and accelerate delivery. Builder-first: code gets written, architecture gets shaped, and teams leave moving faster.
We've shipped across several platform waves—from early mobile to modern AI—and still write code daily. We believe clarity beats cleverness, automation beats repetition, and small teams move fastest with experienced engineers at the keyboard.
Approach
Four operating principles that travel well
Fewer Moving Parts
Start from business goals, then simplify the stack. Anything that doesn't clearly advance the goal gets merged, archived, or postponed.
Readable Over Clever
Code should explain itself. Beautiful names, explicit types, small functions. Comments say why, not what.
Automate the Boring
CI runs linting, tests, and security checks. CD ships green builds behind flags or canaries. Infrastructure lives in code.
AI as Co‑Developer
Acceleration without abdication: strong typing, tests, and CI guardrails keep output reliable while humans decide the hard stuff.
Services
Right‑sized ways to work together
Architecture & Delivery
Untangle performance, stability, or maintainability issues while we ship improvements alongside your team.
Engineering Leadership
Hands‑on technical leadership inside your team — we mentor, set direction, and contribute code daily.
Product Development
Design and implement features and platforms with clean foundations (tests, CI/CD, observability).
